Hi,

We have a client application that connects with salesforce though the API to insert/update data.

Salesforce was down for a few minutes the other day and we saw in the logs the following messages:

"SERVER_UNAVAILABLE: server temporarily unavialable, SERVER_UNAVAILABLE: server temporarily unavialable"

But I am wondering which of the following exceptions were thrown (the exception "name" wasn't tracked in the logs):

<operation name="update">

<documentation>Update a set of sObjects</documentation>

<input message="tns:updateRequest"/>

<output message="tns:updateResponse"/>

<fault message="tns:InvalidSObjectFault" name="InvalidSObjectFault"/>

<fault message="tns:UnexpectedErrorFault" name="UnexpectedErrorFault"/>

<fault message="tns:InvalidIdFault" name="InvalidIdFault"/>

<fault message="tns:InvalidFieldFault" name="InvalidFieldFault"/>

</operation>

Before Salesforce went down our client application was already logged in so the only API call made repeatedly during the downtime period was an "update"

Is there a way to know which exceptions are thrown only thrown when there is a problem with the server (transit error)? so we can resend the message?

we need to make a distinction when the exception is thrown because of bad data or when it is a transit error due to server issue. If it is because of bad data, we prefer to log an error rather than retry again and again.

Could you please help here?
